You can use High Performance Extensible Logging (HPEL) to help diagnose problems in WebSphere® Application Server.
Administrators using WebSphere Application Server need to use log and trace files to determine whether their applications and the server are running correctly.
Logs typically contain information that is of interest to administrators and must be looked at periodically to ensure there are no unexpected errors or warnings.
Trace typically contains information that is useful for debugging application or server problems and can help identify specific problems with individual components.
